and yes if fuel pressure is incorrect then also it can lead to lower volume of fuel injection.

hi guys, my first time on this forum, about me is that i m looking forward to start repairing cars after a long time (10 years), i dont hav really much experience but taking interset and learning everyday by all means.

if i make an input in this subaru case, it seems if external vacuum has been checked, then the internal vaccums leaks can be EGR, PCV or EVAp valve. pcv has been replaced and ithink evap line can be blocked somehow to check if eva valve is culprit.The last one will be EGR as it is little bigger job but always good and recommended to take it out and clean it. this egr valve deal with dirty exhaust gases so tends to get stuck open leading to lean condition.

pls correct me if am wrong.

thanks
